Our cloud service allows you to get started with Structurizr quickly, without needing to host and update software on your own servers. A free account provides a single workspace, plus the basic features to create diagrams and documentation. Diagrams and documentation owned by free accounts cannot be shared with other users. The following paid subscriptions provide 1+ workspaces, and a number of features designed for teams (see the product comparison).
Cloud service subscriptions with more than 10 workspaces are available to purchase by contacting us, and are priced at a discounted rate of $100 per workspace per year, for example:
|1 year subscription with 25 workspace(s)||US$2,500|
|1 year subscription with 50 workspace(s)||US$5,000|
|1 year subscription with 100 workspace(s)||US$10,000|
We also have a version of Structurizr that can be run on your own infrastructure (local servers or cloud), providing the majority of the same features found in the cloud service. A subscription grants you a perpetual license to use the software on your own infrastructure, although software updates will only be available for the duration of a valid subscription. See On-premises installation for more details.
This is designed for installation on a single server, with all workspace data and users being stored on the local file system. The following paid subscriptions provide 1+ workspaces, and a number of features designed for teams (see the product comparison).
On-premises installation subscriptions with more than 10 workspaces are available to purchase by contacting us, and are priced at a discounted rate of $200 per workspace per year, for example:
|1 year subscription with 25 workspace(s)||US$5,000|
|1 year subscription with 50 workspace(s)||US$10,000|
|1 year subscription with 100 workspace(s)||US$20,000|
The authentication add-on provides support for authentication with LDAP and SAML 2.0 - see On-premises installation - Authentication for more details. This is available now, and pricing is a one-off fee of $2,500. Please contact us for details.
The high availability add-on allows for installation on multiple servers for high availability, with a number of options for data storage (e.g. MySQL + Amazon S3 + Elasticsearch). Please contact us for details.
Frequently asked questions
What is a workspace?
In Structurizr, a workspace is the wrapper for your software architecture model, views and supplementary documentation. We recommend that a workspace contains the model, views and documentation for a single software system. See usage recommendations for more details.
Do subscriptions belong to users or workspaces?
A subscription belongs to a user account and, for the cloud service, the paid features are associated with the workspace(s) owned by the user who has the subscription. If you transfer a workspace from a paid subscriber to a free user, that workspace will lose the paid features. Subscriptions cannot be transferred between users.
Per team pricing, not per user?
Unlike typical software modelling and documentation tools, where the pricing is hundreds or thousands of dollars "per user", Structurizr's pricing is designed to be "per team", for whatever your own definition of a "team" is.
"Per user" licensing tends to result in a common anti-pattern where a small number of people end up being responsible for updating diagrams, with the resulting diagrams often being manually exported to static images for inclusion in documentation or wiki pages. We think that good software architecture diagrams and documentation should be accessible by everybody on the team, rather than just those lucky few individuals who are fortunate enough to have licenses for tooling.
Workspaces owned by a paid customer can be shared with free users, so you only need to purchase one subscription for your team.
Is there a trial of the paid features?
Yes, after signing up for our Free Plan, if desired, you can activate a free 14 day trial by using the link on your dashboard. This trial allows you to create up to 3 workspaces and unlocks all of the available features. This is obligation free and no payment details are required. After the trial period, your account will revert back to the Free Plan.
Do you manage credit card details yourself?
No, we use Braintree Payments (a PayPal company).
Which credit cards do you accept?
We accept Visa, Mastercard and American Express.
What's your refund policy?
- Payments for cloud subscriptions are refundable within 7 days of the payment date.
- Payments for on-premises installation subscriptions are not refundable - please contact us for an extended trial if necessary before starting your subscription.
What happens if my payment fails?
If a subscription payment fails for any reason, your subscription will be cancelled, and a 7 day grace period provided. In this situation, we will send you an e-mail with instructions about how to resubscribe to the same plan with alternative payment details.
What happens to my workspaces when my paid plan expires?
Users on the Free Plan can create one workspaces so, when your paid plan expires, the workspace that you created first will be retained as-is. The other, more recent, workspaces will be retained too, but marked as read-only. You can still view the workspace content (via the UI and web API) but no changes can be made.
Can I purchase an annual subscription?
Yes, we can provide a non-renewing annual subscription. Payment can be made via an invoice for bank transfer (SWIFT/IBAN or UK bank transfer), or via a PayPal invoice for payment via credit card. Please contact firstname.lastname@example.org with your business name, address and any purchase order details.
Do you have a W9 form?
No, Structurizr Limited is not a US-based company. We do have a W-8BEN-E though - please e-mail us.
Do you have a VAT number?
No, Structurizr Limited is registered in Jersey (Channel Islands), so we do not have a UK/EU VAT number.
